DIE FOR LACING TIPS.

Specification of Letters Patent.

Patented Apr. 4, 1922.

Application tiled .Tune 18, 1912. Serial No. 704,385.

(GRANTED UNDER. THE PROVISIONS 0F THE ACT 0F MARCH 3, 1821, 41 STAT. L, 1313.)

To all fui/0m t may concer-n Be it known that I, PAUL Vonsfrnrinn, residing at Barmen, lVichlinghauserstrasse 40, Rhenish Prussia, Germany, have invented new and useful Improvements in Dies for Lacing Tips7 of which the following is a specication.

This invention relates to means for forming lacing tips and it has for its object a pair of dies or die members by which a tubular lace onto which is stuck a piece of celluloid is subjected to pressure and heat, so that a stift' and unyielding tip of hornlike consistency is obtained which resists bending and breakage, Wear and tear.

The invention is fully set forth in this specification and more particularly pointed out in the appended claim.

ln the accompanying drawing* l? ig. l is a cross section of the coacting dies. l

Fig. 2 is a plan partly in section.

Fig. 3 shows the lace end provided with the tip.

As described before the lace consists of a tubular braided fabric il as shown in Fig.

l and the tip formed thereon of a piece of celluloid is positioned on one end of the lace7 then 'treated by subjecting the same to pressure and heat. To form from this ma.- l'crial a lacc tip the device Figs. l aud is employed Which consists of a die a which is mounted on a suitable base plate and fixed thereto by a screw insertedin the hole al. This die is provided with a surface ai and has a semicircular groove as, f1 is the plunger die that is movable and for this purpose is operated by any reciprocating means which is connected with said die at the bolt hole 71'". lThe plunger die is provided with a semicircular groove Z that corresponds with groove as so thatboth grooves form a tubular chamher or space c which however isv conical .in shape. At one side the chamber c is closed by a Wall j in which is pierced a small hole g. As will be readily understood the lace end provided with the tip material is introduced into the recesses .3 the dies a, l) being constantly heated by any suitable means as for instance gas, etc., and then the plunger die is pressed against the lace end and thereby the tip is journaled in such a manner that the Celluloid material is intimately connected with the lace the libres of which are embedded therein so that no separation can take place and a smooth and handsome tip is obtained with a rounded end. It Will be easily understood that this effect results from the arrangement of the small hole by which the superliuous celluloid and also gases and smoke may escape. Many trials Which have been made Without said hole have not given the effect now produced.

What l claim is In a molding device .for molding lacing tips of Celluloid or other plastic material, a. stationary die comprising a block having a cut out portion extending from one edge thereof and terminating substantially centrally thereof, and including substantially one half of the thickness of the block, the cut out portion terminating in a curved wall. one end thereof having a flange provided with a semi-circular cut out portion. a block engaging the side of the first mentioned block adjacent the cut ont portion for providing a slot, means for securing the blocks together, a movable die member of a Width equal to the Width of the slot, said movable die member having a concaved end portion, one end of said concaved portion having a flange providedlivith a semicircular cut out portion cooperating With the cut out portion of the li rst mentioned block for providing an opening, and said movable die member having an opening whereby the same may be secured to a movable element.
